Soon after Li Yan became the ruler of Bianliang City, he drew more than 10,000 acres of land for the Chinese Academy of Sciences not far from the palace. Vertex Says X 23 U OM

At that time, Li Yan's move was dumbfounded.

You must know that this area was prepared by Zhao Ji for himself to expand the palace.

Who would have thought that Li Yan would paint all these tens of thousands of acres of land to the Chinese Academy of Sciences?

What's more critical is that the ghost knows, what does this Chinese Academy of Sciences do?

When some people pass by the Chinese Academy of Sciences, they often hear some loud and weird sounds, such as "whooping, wheezing" breathing, like "woo-woo-woo" strange screams, and so on......

Some people speculate that Li Yan raised a group of mythical beasts or monsters in the Chinese Academy of Sciences.

There are also speculations that the reason why the Chinese army is invincible and invincible is because of the help of these mythical beasts/monsters.

In fact, these people's speculations are not unfounded.

In addition to such and such strange voices from the Chinese Academy of Sciences, Li Yan, the emperor, ran to the Chinese Academy of Sciences every three or five days, and stayed for most of the day.

Some women in Li Yan's harem couldn't help but say sourly: "This Chinese Academy of Sciences is about to become the second home of the official family!" ”

The common people speculated that Li Yan went to the Chinese Academy of Sciences to personally feed this divine beast/monster and contact them with feelings, lest they rebel or even devour the master.

This also invisibly added a lot of mystery to Li Yan.

In this feudal society, this can actually strengthen Li Yan's rule.

Of course, the Chinese Academy of Sciences is not a place where Li Yan raises mythical beasts/monsters, but a national scientific research institute presided over by Li Yan himself.

As for those strange sounds, of course, they were not emitted by divine beasts/monsters, but by the train that Li Yan personally presided over the research and development.

Speaking of this train, we have to talk about the steam engine.

In fact, as early as a few years ago, Li Yan, Liu Huiniang, Bai Valhan and others had already developed the earliest steam engine.

This is actually not difficult, even if there are no Liu Huiniang and Bai Valhan, two masters of organs, with the theoretical foundation provided by Li Yan, just find someone who is familiar with the production of organs, and you can build the earliest and simplest steam engine.

But the steam engine is easy to build, and it is difficult to apply it to industry.

In the earliest days, Li Yan wanted to place the steam engine directly on the ship, and wanted to build his own steel fleet.

But until now, it has not been completely successful.

Later, Li Yan proposed the concept of trains.

The Chinese Academy of Sciences began a two-pronged approach.

In the process of development, under the leadership of Li Yan, tens of thousands of scientific researchers made repeated improvements to the earliest and simplest steam engine.

Technologies such as separate condenser, insulation layer outside the cylinder, oil-lubricated piston, planetary gear, parallel motion connecting rod mechanism, centrifugal governor, throttle valve, pressure gauge and so on have been conquered successively.

Finally, in the middle of last year, the Chinese Academy of Sciences developed the world's first industrial steam engine, which was more than three times more efficient than the earliest and simplest steam engine developed by Li Yan and others.

It was also at that time that the earliest and simplest locomotive also came up with a plan.

This locomotive, Li Yan and others originally wanted to do it in one step, that is, directly use all steel development.

But it's just too difficult.

In the end, Li Yan and others had no choice but to settle for the next best thing, mainly made of wood, and only used steel to make their core area.

But even so, it is still very difficult.

Fortunately, there is Li Yan, a person from later generations, to guide this group of people who are willing to study.

Li Yan has put forward the concepts of sand turning, annealing, polishing and other concepts (in fact, these technologies have been used before, but they have not been used in industry), and even Li Yan led people to manufacture the earliest lathes, all in all, Li Yan's military internship when he was a soldier was not wasted, almost all of them were used.

More importantly, Li Yan can practice steel, which is the foundation of industrialization.

And the most important thing is that Li Yan's vision is far beyond the people of this era, and often his small idea can wake up tens of thousands of researchers, and then make research and development a big step forward.

Reduced verse said.

After countless efforts, including Li Yan, the world's first locomotive was finally developed.

And today is the day of the trial of this locomotive.

On such a day, how could Li Yan, who made great contributions to the development of trains, not come to witness it in person?

Therefore, Li Yan came to the Chinese Academy of Sciences early, and then looked at the big, stupid and ugly locomotive in Li Yan's opinion, as well as the six railroad tracks arranged neatly around the Chinese Academy of Sciences.

Speaking of this track, there is also a story.

When the width of the railroad track was determined, the researchers of the Chinese Academy of Sciences did not dare to make their own decisions, so they asked Li Yan to decide.

Li Yan clearly remembered that the railroad track in later generations was 1,435 mm, so the first idea was to give this value to the Chinese Academy of Sciences.

But the problem is that the current unit of length is not the same as that of later generations.

Not to mention the previous length unit of Dazhong, it is almost the same at one time, and it always changes.

The unit of length of the Great China Dynasty was forcibly determined and implemented by Li Yan.

To this end, Li Yan also held a very grand ceremony.

At that time, Li Yan took a step in front of more than 100,000 people, and set that step as "one meter", a unit of length also known as "Yan Meter".

Later, Li Yan announced in public that this was the unit of length of his regime, and stipulated that one meter was equal to three feet, one meter was equal to ten meters, one meter was equal to one hundred centimeters, one meter was equal to one thousand millimeters, three meters was equal to one zhang, and one thousand meters was equal to one kilometer.

Even now, Li Yan took that step, and there was still a Roman carving master in front of the Liaodong Palace in Seoul, carving a stone statue for Li Yan, and the stone statue replaced Li Yan and kept taking that step.

Li Yan's step is only determined to be unbiased, equal to one meter in the future.

Therefore, Li Yan gave the Chinese Academy of Sciences a value of 1,435 millimeters, which could never be equal to the length of the train track in later generations.

Later, Li Yan figured it out, why should he bother with the width of the train track in later generations? He is the founder, and it should be the people of later generations who follow their own footsteps.

In the end, Li Yan repeated his old tricks, took two steps, and stipulated that this was the width of the rails.

It is said that the two steps taken by Li Yan should be two meters.

But Li Yan's two steps were a bit small, and the result was only 1,876 millimeters.

This has become a fixed width between the rails of this world.

By the way, before the development of this locomotive, Li Yan and researchers from the Chinese Academy of Sciences had already developed a steam locomotive, that is, a car that can run under the drive of a steam engine, and the speed of the car is four to five kilometers per hour, which is slower than a person and cannot turn.

But even so, the steam locomotive still brought great hope to Li Yan and tens of thousands of scientific researchers, especially the latter.

This is also the reason why Li Yan and tens of thousands of scientific researchers were able to develop the train.

And this is the time to witness the miracle......
